Proliferative2
- In diabetic rodents, GLP-1 increases β-cell mass via proliferative, neogenic, and antiapoptotic actions ( 1 ). (diabetesjournals.org)
- Insulin secreting beta cells are shown in red, glucagon secreting cells in green and proliferative cells in white. (bioville.be)
Levels5
- When this fails in diabetic patients, too much glucagon contributes to a vicious cycle that exacerbates the already high blood sugar levels of diabetics. (uu.se)
- As expected, the experiments showed that glucagon is secreted during periods of low glucose, while high levels of the sugar efficiently block its release. (uu.se)
- The OLS regression and quantile regression further showed that 25(OH)D was associated with glucagon and fasting C-p levels in T2D patients with abdominal obesity. (researchsquare.com)
- Through qPCR, western blot and confocal analysis, we demonstrated higher expression levels of PARP-14 in αTC1.6 cells with respect to βTC1 cells under inflammatory stimuli. (unict.it)
- Near the thyroid are 4 tiny pea-shaped organs, the parathyroids, that secrete parathormone to control and balance the levels of calcium and phosphate in the blood and tissue fluids. (medscape.com)
Pancreatic islet2
- By comparing the pancreatic cells of type 2 diabetic human donors with those of healthy people, researchers at the University of Geneva (UNIGE) and at the University Hospitals of Geneva (HUG), Switzerland, were able to demonstrate, for the first time, that the pancreatic islet cells derived from the Type 2 Diabetic human donors bear compromised circadian oscillators. (sciencedaily.com)
- Glucagon and insulin respectively secreted from the pancreatic islet α-cells and β-cells are main hormones for regulating glucose homeostasis. (researchsquare.com)
Blood7
- The reason, Hmeadi explains, is that α-cells are normally blocked by insulin and other hormones that are released at high blood glucose from nearby cells. (uu.se)
- Insulin causes muscle and fat cells to take in glucose from the blood. (quizlet.com)
- Furthermore, frozen cells even exceed fresh cells in their blood glucose controlling capacity in the initial study, indicating an enrichment of the more potent cells during the freezing process. (bioville.be)
- Hemoglobin is the part of your red blood cells that carries oxygen from your lungs to the rest of your body. (blfh.org)
- If you have too much sugar in your blood, that's mean your cells can not absorb sugar as well as they should. (blfh.org)
- It produces 2 hormones: vasopressin, which causes blood pressure to rise and regulates the amount of water in the body's cells, and oxytocin, which causes the uterus to contract during childbirth and lactation to begin. (medscape.com)

Epithelial Cells3
- Taste sensations are mediated by taste buds-small clusters of specialized epithelial cells on the tongue, soft palate, and larynx. (the-scientist.com)
- Indeed, elements of the taste transduction cascade occur in many chemoresponsive epithelial cells scattered throughout the stomach, the intestines, and even the airways. (the-scientist.com)
- Brush cells are tall, columnar epithelial cells that display a distinctive tuft of stiff microvilli at their apex. (the-scientist.com)

Intestine1
- In 1996, researchers at the University of Würzburg reported that a-gustducin is expressed by brush cells of the stomach and intestine. (the-scientist.com)
Protein3
- In exocrine acinar cells regulation of intracellular calcium plays a pivotal role in controlling fluid and protein secretion. (rochester.edu)
- IL-1 beta also induces the accumulation of cGMP by the insulinoma cell line Rin-m5F, and both NMMA as well as the protein synthesis inhibitor cycloheximide prevent this cGMP accumulation. (jci.org)
- We have designed a double-stranded adeno-associated virus containing a rat proglucagon promoter (700 bp) driving enhanced green fluorescent protein (AAV GCG-EGFP), to specifically identify α-cells. (bvsalud.org)

Inhibition2
- Pretreatment of beta-cells, purified by FACS with IL-1 beta results in a 40% inhibition of glucose-stimulated insulin secretion that is prevented by the nitric oxide synthase inhibitor, NG-monomethyl-L-arginine (NMMA). (jci.org)
- This is further demonstrated by IL-1 beta-induced inhibition of glucose oxidation by purified beta-cells, mitochondrial aconitase activity of dispersed islet cells, and mitochondrial aconitase activity of Rin-m5F cells, all of which are prevented by NMMA. (jci.org)
